For the gel compression fracture test, a universal testing machine equipped with a 100 N load cell and a compression platen with a diameter of 15 mm is used. The test setup includes a flat plate on which the sample is placed. Compression is applied at a speed of 1 inch per minute. The compressive force exerted on the gel is measured until a drop in force indicates the point of gel fracture. A higher compressive force indicates greater resistance to gel fracture.
